DISTILLING APPARATUS.

SPECIFICATIONfOrming part of Letters Patent N0. 749,368, dated January 12 1904,

To a whom it may concern:

. I have particularly in view as an objectthe con- Be it known that we, ADOLPHE C. G. DUPUIs,

' a residentof New Orleans, in the parish of Or- I I, I leans and State QfLOuisiana, and WILLIAM S. FELL, a resident of VVaveland, in the county of Hancock and State of Mississippi, citizens of the United States, have invented new and useful Improvements in Distilling Apparatus,

I I i of which the following is a full, clear, and exstruction of a still or alembic which shall be exceedingly simple, positive in its operation, and one whlch shall cause the lightervapors generated during the courseof distillation to escape from thechamber of the still, while the heavier vapors thereof shall be conducted from said chamber by conduits and shall leave the y wcasing or chamber by difl'erent exits than the lighter vapors. I

A further object of the, present invention is i to construct astill which shall prevent the rei turn of the condensed oils or other materials I i i into the retort, thereby preventing the redis- I 5O tillation of the same with the entire mass.

I A further object of the invention is to force the vapors into and through a peculiarly-constructed passage-wayrunning the entire length of the still which shall cause the lighter vapors to be separated from the heavier vapors, whereby the lighter and heavier oils may be obtained in a comparatively short time.

I If desired, the walls of the conical orvapor I i. I g chamber may be double or formed of two separate walls and the space between the same filled with a non-conductible cement, asbestos, or the like which shall prevent the premature condensation of the vapor upon the walls of the still, thereby preventing the dropping of the distilled oils back into the retort.

With these and other objects of a similar nature in view our invention consists in the construction, combination, and arrangement Application filed February 18, 1903. Serial No. 143,951. (No model.)

of parts, as is described in this specification, delineated in the accompanying drawings, and set forth in the appended claims.

, Reference is-to be had to the accompanying drawings, forming a part of this specification,

in which similar characters of reference indicate corresponding parts in all the figures.

Figure 1 is a central vertical longitudinal section of an apparatus embodying our improvement, taken on the'line 1 1 of Fig. 2. Fig. 2 is a transverse vertical sectional view of the same, taken on the line2 2 of Fig, 1;

and Fig. 3 is a perspective view of a stillembodying our improvements.

Referring now to the accompanying drawings, 1 designates the main casing or body portion of the still, which forms a retort for the ,oils or other liquids to be vaporized.

While this portion 1 of the still may 'beof any suitable shape or form, yet we prefer to make the same substantially cylindrical or semicylindrical in cross-section, and the wall of said retort or the portion exposed to the heat or fire is formed with a corrugated surface 2, which may be ofany desired character and thickness and serves a purpose to be hereinafter described. From the upper portion of said cylindrical retort extend the converging walls 3 and 4, preferably formed integral with the cylindrical body, which walls come to a point or apex 5, the chamber thus formed by the walls 3 and 4 being approximately conical in shape. The shape and relation ,of these walls forms a very important feature of the present invention, as will be hereinafter noted.

Converging upwardly from the points of juncture of the inclined walls 3 and 4: with the cylindrical retort 1 are two plates 6 and 7, which are slightly curved, as at 8 8, the upper ends of said plates 6 and 7 being spaced apart and extended in substantially parallel lines. These walls, which are used to conduct the heavier vapors, may be single or double and when double are preferably filled, as at 9 9, with a coating of non-conductible cement, asbestos or the like which will prevent the premature condensation of any vapor on the walls of the still, thereby preventing the dropping of the distilled oil back into the body of the retort. Extending transversely of the body of the apparatus 'and secured approximately at the point of juncture of the walls 3 and 4 with the retort is a horizontally disposed framework 10, which forms a support for a number of perforated screens composing the mattress or partition 11, which mattress or partition is filled or loaded with any suitable chemical reagent. The body portion 1 of the retort or still is provided with an intake duct or conduit 12, through which the oil or petroleum is admitted, and may also be provided with any suitable outlet, as at 13. After the oil has been admitted to the still the cylindrical portion thereof is exposed to a fire or other suitable heating agency and vapors are generated from the fluids, the corrugated bottom preventing the bottom from cracking while expanding and contracting through the influence of the heat and in addition thereto increasing the heating-surface, thereby effecting a saving of fuel, time, labor, and chemicals. The vapors on rising from the fluids pass upward through the screens, which are loaded with the chemicals, and are filtered, decolorized, and deodorized before condensation, thereby yieldinga high grade of commercial oil. The lighter vapors ascend to the apex 5 of the still and are drawn or forced out through a pipe or other suitable outlet 14:, communicating with said apex, while the heavier vapors,

clinging or following the converging walls of the conical portions, travel downwardly and pass through the pipes or conduits 15 and 16 to a communicating outlet 17. Both the outlet at 17 and that at 1 1 may be connected with any suitable refrigerating or condensing apparatus. (Not shown.)

It will be observed that the conical passageway running the entire length of the still, in connection with the conical hood, prevents the return of condensed vapors tothe body of the still in addition to obviating the possibility of premature condensation, thereby greatly decreasing the time necessary for the performance of the act of distillation. The,

conical hood, which is a part of the still, forms a superior condenser and by its form of construction carries the vapors at once from the conical passage-way to the several discharge-pipes, which results in the immediate distillation of the several grades of oil.

While we have shown and herein described one particular embodiment of our invention, we wish it to be understood that we do not limit ourselves to the precise details of construction herein, as there may be modifications and variations in some respects without departing from the principle of the invention or sacrificing any of the advantages thereof.

Having thus described our invention, we claim as new and desire to secure by Letters Patent 1. A distilling apparatus, comprising a liquid-containing receptacle, the wall of said receptacle having corrugations formed therein, a conical vapor-chamber mounted above said receptacle, a foraminous chemical-containing partition between the chamber and the receptacle, upwardly-extending converging plates mounted in said chamber, a filling of nonconducting material for said plates, an outlet for the lighter vapors at the apex of said chamber, and outlet-conduits for the heavier vapors, lying between the walls of the chamber and the aforesaid converging plates, said conduits converging and joining a common duct outside said chamber, substantially as set forth,

2. A distilling apparatus, comprising a liquid-containing receptacle having an inlet and an outlet for the liquid, the wall of said receptacle being corrugated, a foraminous chemical-containing partition separating the receptacle from the chamber, upwardly-extending converging curved plates mounted in the chamber above said screen, said plates being spaced apart at their upper ends, an outlet for the lighter vapors at the apex of said chamber, and outlets for the heavier vapors, formed at the bottom of said chamber between the upwardly-extending plates and the walls of said chamber, substantially as set forth.

In testimony whereof we have signed our names to this specification in the presence of two subscribing witnesses.
